The Buenos Aires Police raided a 16-year-old boy's home in Martinez. The teenager had already threatened at his school in March and then seized an arsenal.

He now had ammunition on his light table.. "A catastrophe was avoided, it is counterfactual but it is so," says the investigator who managed to arrest the boy. The boy is a former student of a private school in the area, the exclusive Riverside School, in Acassuso, which he had threatened in March. He is being held at the San Isidro DDI.
